Why the study?
Do the SphygmoCor and Omron devices accurately estimate central-to-brachial pressure amplification compared to invasive catheter measurement in individuals undergoing cardiac catheterization?
Do the SphygmoCor and Omron devices accurately estimate central-to-brachial pressure amplification compared to invasive catheter measurement in individuals undergoing cardiac catheterization?
Both the SphygmoCor and Omron devices have similar accuracy in estimating pressure amplification compared to invasive catheterization, though they may require device-specific diagnostic criteria.
No takes yet. Share an insight, caveat, or question.
Limited agreement with invasive measures cautions against clinical use of either device for amplification estimation; leaves open validation of device-specific thresholds.
Ding et al. (2012) studied this question.
